Waalaikumassalam mama! 30 weeks and getting the jitters adalah normal sangat, honestly, almost every first-time mum I know felt exactly like this, and they all came through fine. Apa yang paling penting is to trust your body, attend your checkups regularly, and surround yourself with good support (partner, family, trusted midwife, whoever makes you feel calm). The nervousness you're feeling sekarang is actually good, it means you're taking this seriously and preparing mentally, so keep that energy! Remember, your body has been preparing for this since day one, and you've got this mama.
